Researchers are investigating whether blocking serotonin in the brain could help treat PTSD and anxiety disorders. Image credit: Producciones Visualix/Stocksy. People with post-traumatic stress disorder (PTSD) live with terrifying memories of traumatic events. Psychotherapy is the primary form of treatment offered to people with PTSD and other acute fears. Drugs may supplement such treatments. A new study...

UPPSALA UNIVERSITY In asthma, the airways become hyperresponsive. Researchers from Uppsala University have found a new mechanism that contributes to, and explains, airway hyperresponsiveness. The results are published in the scientific journal Allergy. Some 10 per cent of Sweden’s population suffer from asthma. In asthmatics, the airways are hyperresponsive (overreactive) to various types of stimuli, such as cold...

A class of immune cells push themselves into an inflammatory state by producing large quantities of a serotonin-making enzyme, according to a study in mice led by scientists at Weill Cornell Medicine. The study, published in Immunity, found that the inflammatory and infection-fighting abilities of the cells, called type 2 innate lymphoid cells (ILC2s), are...
TEXAS TECH UNIVERSITY HEALTH SCIENCES CENTER To address the receptor dysfunction associated with several serious neurological diseases, Michaela Jansen, Pharm.D., Ph.D., from the Texas Tech University Health Sciences Center School of Medicine recently completed a study that provides novel insights into a protein-protein interaction that may one day lead to more effective treatments for these...
by John Hewitt , Medical Xpress Neuroregeneration entails not only neurogenesis, but also regrowth of lost connections and birth of non-neuronal cells. While adult neurogenesis in humans is only known to occur definitively in a few precisely circumscribed regions of the brain, work in other species suggests that science has only scratched the surface of...
